Hi. I have a general question about the broker and the protocol (not specific to a particular client).
How do I efficiently discover the latest timestamp? By efficiently, I mean: (1) with a fixed number of API calls and (2) without fetching any messages. I can get the earliest timestamp by doing a ListOffsets call with a time far in the past. This will return the earliest offset plus the timestamp for that offset. (Annoyingly, if I make the call with a timestamp of -2, I get back the earliest offset but -1 for the timestamp.) There doesn't appear to be an equivalent way of getting the latest timestamp since the API returns the first offset/timestamp *after* the provided time. If I make a ListOffsets call with a timestamp in the future, I just get an offset/timestamp of -1/-1. I can obtain the latest offset by doing ListOffsets with a timestamp of -1, but as in the -2 case that returns the desired offset and a timestamp of -1. Further, there is no API to go from offset to timestamp without fetching a message. Am I missing something? If this is all correct, it seems like what would be most helpful is if the ListOffsets API returned the accompanying timestamps when the client uses the magic -1/-2 timestamps in the request. Caleb
